Jason Sutherland Posted October 22, 2011 Report Share Posted October 22, 2011 hey guys, Â i have a MK1 escort with a 6 dial dash. Link g3 with g4 firmware running a turbo sohc2000. question is the tacho had a inductive loop that the power wire to the coil would normally run through. this is how the tacho recieved its signal. is there a way i can replacate this by triggering some sort of solid state relay powering a resistor through the inductive loop? or am i way off the mark. Â Cheers Jason Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted October 22, 2011 Report Share Posted October 22, 2011 Didnt it take a neg trigger off the coil like most rev counters ? What ignition setup are you using now ? And have you tried simply inputting an aux out signal to the tacho input ? Whilst not ecu specific, you could ask over on the Turbosports Forum. Lots of Mk1 Escort users there, and I'm sure someone has come across this before Quote Link to comment Share on other sites More sharing options...
Jason Sutherland Posted October 22, 2011 Author Report Share Posted October 22, 2011 nah, well not my one, it has a loop wire that you unplug and wrap around the power feed to coil then re connect. im using single coil with dizzi running from link. it needs to replcate a load simular to a coil to make the tacho go. yea i should ask in the uk, just thaught the people at link mite have come across this before.

Stevieturbo Posted October 23, 2011 Report Share Posted October 23, 2011 If you're using a single coil and dizzy, surely nothing much has changed ? Just route the trigger wire to the coil -ve terminal through the inductive loop. Or the power wire to the coil. The actual coil operation is no different than previous ?

Jason Sutherland Posted October 23, 2011 Author Report Share Posted October 23, 2011 true, except it will mean stripping the loom back and re-routing the feed wire. found out it called a impulse tacho, common for the 60's and early 70's. triggered by pusles on current rather than voltage.

Simon Posted October 30, 2011 Report Share Posted October 30, 2011 You will have to get the pickup on to the coil negative wire. Quote Link to comment Share on other sites More sharing options...
